Examples
example 1
[0042]An organic acid silver (C7H15COOAg) compound of 39.8 wt % was dissolved in a solvent of xylene of 59.7 wt % and then uniformly mixed with multi-walled nanometer scale carbon tubes (MWCNT) of 0.5 wt % to form a mixture of the Example 1. Then, the mixture of the Example 1 was coated on a substrate made of polyethylene terephthalate (PET) by a spin coating process to fabricate an electrically conductive film of the Example 1. The fabrication condition of the electrically conductive film of the Example 1 was implemented by a heat process consisting of a background temperature of 120° C. and an auxiliary energy of far-infrared light to perform a sintering process.
